Abstract: A nonlinearly broadband tuneable energy harvesting device has been designed, fabricated, and tested based on the nonlinear dynamical response of a parametrically excited clamped–clamped beam carrying a central point mass ...

Abstract: In this work, for the first time, an energy harvester based on the nonlinear dynamical response of a parametrically excited cantilever beam in contact with mechanical stoppers has been fabricated and tested; a 145% increase ...

Abstract: In this work, two model identification methods are used to estimate the nonlinear large deformation behavior of a nonlinear resonator in the time and frequency domains. A doubly clamped beam with a slender geometry carrying ...
